For some reason my phone will not boot into recovery. I have tried booting into recovery from the system and via adb. Takes me straight to bootloader. Strange thing is when in bootloader/fastboot mode my computer will not recognize my device in adb when connected, but when I am booted into the system the phone is recognized in adb. I think I have to reflash my recovery (twrp v2.6.3) but originally I flashed it with goo manager, which seems to be down atm. My question is how do I get my device recognized while in bootloader/fastboot again so I can manually flash twrp, and what were the commands to properly flash the recovery via bootloader/fastboot. I did do a search but did not find specific results that answer my questions. I know I've read about this happening but I cannot remember where. Tia.
Edit: FIXED!!!Needed fastboot in same directory where adb exe was located. Commands were able to be run to flash recovery from fastboot.

Hello,
So I have a P7 at B126. I tried rooting it with kingroot and tried to install TWRP. I got to the part where you have to use fastboot to flash the img and it fails so I gave up. Now I am trying to get into recovery and I can't. It just either goes to a black screen or a Boot failed screen.
Thanks in advance
Hi, I'm a little confused right now. Explain what you did so far a bit more detailed, so we could help you.. Which instruction were you are following? What was the exact error? Is your bootloader unlocked? Can you boot normally?

I can boot normally.
What I did was this.
I followed the guide to root my phone. Rooted it and then tried to install the TWRP custom recovery. It failed at the installing the recovery for some permission error. So I stopped trying to install it. Now I apparently don't have a recovery at all.
I also installed some root apps like SetCPU, Xposed(Which didn't work), SuperSU(Which didn't Work)
If I try to adb reboot recovery it just takes me to the boot failed screen with the android logo on it. If I try using the Power + Down button it just shows me the huawei ascent P7 screen and just go black.
Also when I go to the fastboot/rescure mode it says my bootloader is unlocked.
Thanks for the reply.
Ah okay. So, boot into the fastboot mode, put the recovery.img in the adb folder on your pc, run cmd and type 'cd c://..' (location of adb folder), then 'fastboot flash recovery [name of recovery.img]' (for example 'fastboot flash recovery recovery_twrp.img'). Now you should get a working recovery.
Are you sure you really got root access? Eventually due to this you got the permission error..

I do because adb has admin permissions but fastboot doesn't. I tried that with trying to flash twrp on my p7 but i get a failed error after like a second I the command. So I tried flashing a stock recovery and it throws the same error in fastboot.
When I type fastboot devices I get this
? fastboot
No id for my phone but adb sees it.
Ok, your pc does obviously not recognize the p7 in fastboot mode. Did you install the Hi Suite? Through this way you should get the correct drivers (maybe even update/reinstall). If this does not help, I think I can't help you, sorry. You may wait for more help or google what do when the device isn't recognized in fastboot.
Just flash the newest SuperSU.zip when you got a recovery.. That should fix problems with root apps/ the su binary.
Offtopic: I'm not sure if you noticed, but, you're running a pretty old firmware.. You may think about updating

Hi Suite installed and correct drivers are loaded(I hope) and yes thats why Im trying to get this fixed because it wont even let me update firmwares
Try on another pc.. You could also try flashify (look in Google play), but in case of a softbrick you have real problem. Do this on your own risk, most times nothing bad will happen, but it could!
I would recommend to flash the stock recovery, update up to B621 and then installing a custom recovery.
can't boot into recovery

Hi mate.
1. Use your pc, Go shuame.com and download "rom flash program".
2. Enter fastboot&rescue mode and connect your phone and PC
3. The program will recognize your phone.
4. Download anyrom and flash by the program.
The process will not complete but you will have Shuame recovery.
But my case it didn't work properly
5. I downloaded CWM from here "pan.baidu.com/s/1dDq0qcT" password :bttc
Start this program with connect your phone and press nomber 1 and ENTER.
I don't exactly remember my phone was on fastboot & rescue mode or recovery mode.
But I could get recovery and did rom flash so it was fixed.
*****from: Godfrey Peligrino ---sorry i dont know how to post BUT, this guide helped me with my p7 L10 B619..just connect it to pc and let it boot over and over and when pc acknowledge you phone..click rom and just wait if not do it again..hope this will help you too..the writings is on chinese so just copy the english thumbnails before you proceed to download...(QUOTE) THANKS TO THE GUY WHO POST THIS....HE IS TOMODACHI5..
I have not received the OTA update to Marshmallow yet and getting impatient so I'm attempting to sideload the update myself. I've installed the SDK and drivers. The device is listed when I use 'adb devices' at the command prompt and it allows me to boot into the bootloader. But from there it disconnects from my computer and I'm not able to push the update to the device. I get "error: device '(null)' not found". Any advice?
In the bootloader you use fastboot, not adb...
I rarely use adb, but I do believe you need to be booted into Android or the recovery (a custom one).

Ok, but all the instructions I'm finding online to sideload the OTA say to type "adb sideload [the full name of the file].zip". This is after enter Recovery Mode and select "apply update from adb"
I typed "fastboot devices" and my device came up in the bootloader. I click into Recovery Mode and the computer makes the disconnect sound. That's where I'm cut off.
Have you tried unplugging and plugging in the usb again after entering recovery?

I ended up trying NRT and caused even more problems at first, so I ended up just flashing the update instead of sideloading it. I was freaked out for a while because it was stuck in the boot sequence but as of right now, it's working and I have 6.0.
Yay!
ok, sideloading is for twrp recovery. but thats not needed anymore as you can just move files in and out of twrp without adb. flashing factory images is only via fastboot while you are in bootloader. adb and fastboot are different.
Hey,
My phone is stuck in the fastboot mode, without any OS, nothing works... no Recovery ,...
S-ON, no-debugging usb, Bootloader locked and can't unlock him... I already tried with htc-dev, everything works but nothing appair on my screen to confirm the unlocking.
I'm really stuck, searched lot of things on google, ....
I used fastboot, and ADB, the first one recognize my device, but the last one not. I can't boot on RUU mode neither.
Any ideas?

The very first thing I recommend you to do, is to download the right recovery and install it via command
Code:
fastboot flash recovery recovery.zip
Let me know if you run into any further troubles.

Hi,
Frist in boot loader check your OS version it should be something like 2.19.401.2 or lower than this.
NB: ALWAYS TRY WITH MORE THAN 75% BATTERY, AND THAT FOR ANY CODE TO WORK PROPERLY, MAKE SURE TO SELECT FASTBOOT BY POWER KEY IN BOOTLOADER
Anyway, if you can enter fastboot, then you have some chance of recovering your device and because you have S-Off it is going to be a bit difficult.
First download this stock boot file : https://mega.nz/#!lEAVwRSL!wrP2hi6GEYLeJaPf2ssZo9wCtSi7E4yfyUHgh3Q3XSs
Then place this file in the ADB folder, then run command :
To flash boot file command is:
Code:
- Fastboot Devices (this command is important to know if the device is connected and accepting and responding commands)
- fastboot flash boot boot_signed.mg (assuming this is the name you saved the file with)
- fastboot reboot bootloader
Also download Stock Recovery: https://mega.nz/#!gVJE1Bxa!6SwXStAD8p-XlnQiPkRcdNo_ITFD1ykn-tN6wIBVi1I
Place this in ADB folder and run command:
Code:
fastboot flash recovery stockrec.img // (assuming that is the name you have saved the file with), only after flashing this you will know if the device has any OS, if OS exists it will boot up.
fastboot erase cache
Attempt and let us know how it went...Good Luck
So I recently tried to flash TWRP onto my HTC 626 and it seems like everything went well except a completely random group of inputs just loads my phone into fastboot list as follows:
Trying to enter recovery mode from menus
Trying to enter recovery mode from adb
Trying to perform a factory reset from menus
Plugging the device into a pc while powered off
The phone can still boot into the os and it runs just like normal. I have been frantically googling the problem but I have no idea what is going on.
I would have just done a reset but it just loads into fastboot.

Guess what? I just might be able to save the day, mighty mouse style. Are you ready for this?
Try this out and see if it works for you like it worked for me.
But before you do this, I am on the MM-update android 6.0.1...this was what I used for this particular os. If you've update to Marshmallow already, please continue with the following......
Download these files first to your pc.
Twrp recovery - https://goo.gl/sO4Huz
BETA-SuperSU-v2.62 - https://www.androidfilehost.com/?fid=24269982087018189
Credit to my buddy IsaacGuti for the files.
fastboot flash the recovery
Make sure to either rename the Twrp recovery image to "recovery.img" before flashing or be sure to type the exact name of the twrp image file name verbatim. I'd suggest renaming it to "recovery.img just to be on the safe side.
in command prompt, it should look like this when you type it in "fastboot flash recovery recovery.img" without the parenthesis
( "<----These guys to the left....don't add those in)
To make it easier, just copy and paste what's in the parenthesis into the command prompt.
flash the supersu.zip in recovery. (Meaning after the flashing of the recovery is successful, then reboot into TWRP recovery to flash BETA-SuperSU-v2.62) But Don't forget to move the BETA-SuperSU file to your internal sd on your device.
If you've done all of this, you should have success. Just send me a virtual HI-5 and we're all good:highfive:
Hi, i can't get my PC to detect my phone under Fastboot with ADB so i can't do anything through there but i wan't to update my ZCX Recovery. In the installation notes it says "You can flash by either Fastboot method or TWRP methods "but what "TWRP methods" means and how to flash it?
TWRP method mean is if your phone already has TWRP recovery before and wanna change or update it..you can flash new TWRP via your current TWRP.
But anyway.. why your phone while in fastboot mode can't detected by pc.and what command you're typing to check in fastboot mode??, i mean are you sure you're already installing all driver that adb and fastboot needed..?, and are you sure you're already typing correct adb and fastboot command..?
Because recently i see someone thread that asking the same problem like this too (more or less) in en.miui.com forum too..he/she is wrong typing command while he/she's phone in fastboot mode, he/she's typing adb command while the phone is already in fastboot mode, of course adb can't recognize it.
I don't know this is you too or another person.
